Actually, that's a point.
If its' the 31st of Jan, then +1 monthdelta will be 28 Feb and another +1
will be 28 March whereas 31st Jan +2 monthdeltas will be 31 March.
That's the kind of thing which really needs to be documented, or I think
people really will make mistakes.
For example, should a monthdelta include a goal-day so that the example
above would go 31 Jan / 28 Feb / 31 March?
